I feel it would be easier to understand documentation something like "Returns true if the given stealer was derived from this worker".

I don't feel this method name is easy to understand, but I'm not sure what the good name would be.

Currently it's not possible to tell if a Worker and a Stealer point to the same underlying queue. This make it difficult to tell which stealer to remove from a list and you have a local Worker on hand, or skip stealing from when given a global list of stealers. The implementation just forwards to Arc::ptr_eq on the inner buffer. Added a doctest as well.
